What befuddles me is what's taking so long on axing that fine ST coach of ours (if you can actually call him a coach)

The way they are handling all of this is very strange.

Ligs is a done deal, surely. Is there any doubt that he needs to go?

You can't possibly convince me that ALL of the offensive issues go back to the oline. It's Arians who is responsible for designing the offense and supervising the offensive staff. Perhaps Tomlin is trying to save face by allowing Arians to leave, rather than giving in to pressure from fans and the organization?
